8+1 Channel CWDM MUX/DEMUX, C47–C61 + 1310 nm, Low-Loss Monitor Port, Dual Fiber, LGX
The GLOBALfiber G-CMUX-09-4761-LL-MLU is a fully passive 8-channel CWDM MUX/DEMUX designed for dual-fiber point-to-point transmission.
It combines 8 CWDM wavelengths with a 1310 nm wideband service port and a low-loss monitor (MON) port, enabling efficient aggregation, legacy traffic coexistence, and simplified network monitoring.
This compact LGX module is ideal for fiber-constrained environments and is widely deployed in telecom, data centers, broadcast & TV, cloud infrastructure, finance, and government networks.
